You start stroking your cock

If Emma wants you to please her friend and do what shewant, who are you to argue, you think. If Isabella wants to see you jerk off you should obey. So you start stroking your cock. You're already so hard and so ready to go - you're dick is more sensitive than it used to be.

A couple weeks ago, you think, you don't think you'd have been able to cum standing up in front of Emma and her close friends. You would have been too self-conscious, but that's not really an option for you anymore. You have to be a good boyfriend and do what your woman - or maybe now it's women - want. Plus your sex drive has been on overdrive. If you didn't empty your balls regularly you worry they might explode.

Isabella cheers you on a bit while Sophia continues to half look away, but honestly she's struggling not to watch. Emma has a smug smile on her face.

Suddenly you start to loudly approach your orgasm and then your white semen begins to spurt out of your cock, shooting forward and landing a foot or two in front of you, splattering on the ground. You shoot rope after rope of cum - maybe a dozen or more spurts. Even Sophia remarks that she's never seen anything like it - even in a porn. The ground looks like a half dozen guys just had a circle jerk.
